Profile: MICO, Incorporated is an ISO 9001 certified company. We design, manufacture and market quality hydraulic & electrohydraulic components and systems for heavy-duty, off-road vehicles and equipment. Hydraulic brake valves are designed for use with vehicles that are equipped with other hydraulic power devices. This design feature eliminates the need for a separate power brake unit or separate hydraulic fluid system. The sliding caliper brakes are offered in spring, hydraulic or mechanical models.
